First, there WILL be guilds, its only a matter of time before they incorperate the guilding system into the game. Second, what would this so called "Help" tab consist of anyways? Honestly, if your looking for help... isnt that what the FORUMS are for? FAQ's, players, and GM's are always out and about. I, help many players. I answer questions, and do many things that benefit other players. With players like me and the fore-mentioned, there really is no need for a "help" tab.
As an added bonus, and to support my statement. If theres anything you need "help" with. Message me, I'll be glad to help you. Promise ;)
